COUNTER-MOLDING MACHIE TE.

To all w/mmz't may concern:

Be it known that I, RoswnLL A. Lancer, a citizen of the United States,;residing at Townsend, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Counter- Molding Machines; and I do hereby declare Specification of Letters Patent.

not withits detailed description, it may be pointed out that it consists of molds for shaping the counter which comprise two side molds and a center mold, and means for operating the molds so as to cause the centhe following to be afull, clear, and exact description of the invention, such will enable others skilled in the art'to which it appertains to make and use the same.

The present invention relates to an im provcmcnt in counter .molding machines. The object of the invention is to reorganize and improve counter molding machines and,

to produce a new and more cfficient machine for molding counters.

To the above ends the invention consists in the counter molding machine hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating the pre ferred formof the counter molding machine, Figure l is a front elevation ofthe machine; Fig. 2 is a rightside elevation; Fig. 2 "is a detail illustrating the toggle o1: ming and closing cams; Fig. 3 is a left side elevation; Fig; 4 sectional ter mold to miter the space between the side molds when they occupy their open position and to cause their closure upon the center mold and the exertion of considerable pressure upon thecounter carried by the center mold to cause it tobe shaped to the mold. During this operation a projecting flange'of the counter is bent over and pressed against the front surface of the' center mold by a. wiper which passes over the surfaces of the three molds while they hold the counter tightly compressed between them. The center mold is actuated by operating means to move from a position. of clearance to a position of operation and then to be moved into in accordance with the. disclosure hereinelevation; Ifigs. 5,, 6 and 7 illustrate details of construction of the dofier; Figs. 8, 9, 10, 11', 11, ill, ll and-11 illustrate details of construction-oi the feeder; Fig-12 illustrates live positions which the feeder and associated parts occupy during the opera tion oi the machine; Figs. 13 and 14 are rcspectivelv a side and front elevation of the male or :entcr mold and its carrier; Fig. 1-5 is a front view of the center mold when it is swung outward showing the position of the dofl'cr with relation to it in .i'ro nt elevai tion; Figs. 16, 17 and 18 illustrate details of construction of the counter compressing to the molds himself. This is of importance, i

eccentric and associated parts; and Fig. 15)

illustrates the molds and the means for heatin g them. I

The ill utrated embodiment of the counter moldingmachine is described as follows: Preliminzu'y'to a detailed description of the machine and its parts, for the purpose of presenting a brief outline description of the machine which will conducc to a clearer understanding of it when described in connecafter set forth. The machine is also provided with a fccdcr and feeder operating means to which the operative presents the counters and which, in turn, feeds the co un tors one at a time to the molds. Afterv the molding operation is completed and the molds are separated, the center mold is swung to outward position, and the dofier,'

The wiper is The molds are. provided operated by suitable means, removes the molded counter from the center mold and discharges it from the machine. The machine. therefor-e, is one in which the operatire is not equired to present the counter.

as it eliminates all danger of injury. to the operative bv catching his fingers in the I molds. "1. he o 'ici ation after the counteris presented to the feeder 1S entirely automatic and is conducted without the intervention of the operative. I

The counters to be molded are made of leather-board. leather or paper, and are flat blanks having. 'skivcd edges of the usual form. Counters of these materials, when.

, subjected to the molding operation tinder the action of the hot dies, are so changed in compos'cion by the pressure and; heat that they not. only retain their shape after the molding operation but are more or less weterprooted by it. This is a feature of the machine for molding the counters whichils of considerable :mportance, as it is desirable that the counter, after it is made up into a,

shoe, should. retain its shape even after it I been wet. I

- ezids and take into correscondirlg recesses in the side molds carrier 14 which is secured the-$01) oi the frame 15 of the maichine; The side molds 11 have a recess which rcceives'tlte pin 16 which,- when it 13 raised and lowered, opens and closes the side molds.

' lhis pin may be called the side molds clos mg pin and isfcerried in turn by the block 17 which sreceiyed in a guidcwey 18in the front pert'oi the top of the 'framc 15 of theme'chine. T-liis'bloclr receives also the pin' 20 by which it is raised and lowered. The pin carries friction disks 21 which embrace the opposite sides of thcslottcd plate 22 by which the pin is raised and lowered. The spring pressure. by which the friction plates '21 engage the plate 22 is exerted by e. pringill on the 'pin20 which is adjusted by means of the nut25. The plate 22 is carried by the vertical links 26 which are secured to the two sides of the pate on opposite sides of the pin 2G endure connected at their lower endstothe center mold can'ier.

The ebovcdescribed arrangement is such v that when the center mold carrier rises, it

moves the links 26 upward, thereby causing the block 1? to be lifted and inturn lifting the mold closing pin 16 so as to close the v side molds 11 upon the center mold; This near its closing movement of the molds upon the center mold 'is for the purpose of bringing them to a position of pressure, not for the purpose of exerting molding pressure upon the counter. The side molds are required to open. endclose by the swinging movements to allow the entrance and Withdrawal of the center mold into the space between theside molds the center mold being smaller 1 lower end than it is at its upper end.

The center mold 10 is provided with a shank .30 having a cylindrical, condyle-like enlargement 31 on its lower end which is received in a corresponding shaped recess in the center mold'lmsc 32. The enlargement is adapted to turn in therecess in the whose 32 and it is held from accidental mover mes es menttlrerefrom by the pin Ow ing to the center mold carrier l0 and held from rotation on thcsaid carrier byfthe pin 41. .When itis desired to adjust thccenter mold base 32 Vertically, the collar-364s turned by means of a pin which .is thrust into the holes in its periphery. The center mold-base 32 is adjusted front and rear 'by mom oi -the screw l2 held by the screw holder 43 secured by tliebolt '44 to the center mold carrier-40; The center mold carrier 40 is piro'ta'lly ,mo untcd' upon the center mold carrier lever- 45'still Upon eechside of the center mold carrier there is a depending mu l-7, the lower ends of which are connected by/ the links 48 Withthcirame of the machine, cs shown'in Figs l' and 4:. The

center mold cerrier lever" Kris pivotally supported upon the frame cl the-machine at 50 to rock toviard' andfromg the side molds, and at its lower end is connected by means of etogglev with the counter compressing eccentric.

The toggle consists of the link 51 giiv otally connected to the lower end'ofthelever 45 and the'link52 pivotally connected at 53 to the 'link:5land mounted upon the counter compressing eccentric 54-.

The link52 consistsof two members, the.

upper member ,55 end the lower member 56 bolted together by the bolts 57 These two the eccentric 5%. The journal 58 is connectlinlcmembers 55 --and 5,6 embrace the eccentrrc gem-goal 58' which is directly, mounted on med-by the bolts 60 with the spring follower olfegainst-wnich the spring 62 takes, the

other end ofthe spring taking against the I .inembcr 5%. The spring follower 61 is pro-, vlded with -a pin 63 which is received ina,

rcce% 64 in; the member 56. The, toggle is straightened byi -mcans of e toggle-strei litening lever (Soto the end of which a li is secured which is attached to the knuckle pin. 53 of the toggle;v After the toggle is straightened, the counter molding pressure is exerted on the center mold carrier" leverv 45 by the countercompressing eccentric 54:.

The spring: 52 is for the purpose of permitting ltz yieldll'lg of the parts in case of an extraordinarily thick counter or the accidental insertion of two counters in the machine at one time, and by reference to, Figs. l6, l7 I and lS'it will be seen that in this case the v ecccxltric moves the journal 58 in the direcmesses tion to cause compressing pressure to be ex erted upon the center mold carrier lever 45, but in case that lever is held from movement by extra. thickness of material in the molds and cannot move, then the journal58 is permitted to move in compressing direction by machine. The hub 70 of the lever 65 is provided with two camarms. One of these cam arms, the arm 71, carries a, cam roll at its end which engages the cam disk 72 mounted on the cam shaft 73 supported in suitable bearings on the frame of the machine. This cam arm may be called the closingcamas its swells move the straightened lever in the direction to close the toggle. The other cam arm, the arm 74, formed on the hub of the straightener lever 65, is provided on its end with the cam roll 75 which engages the cam disk 76 also mounted on the shaft 73. K This cam disk is for convenience called the. toggle opening cam, as itswells move the lever 7% in the direction to cause the opening or breaking of the toggle.

The above-described arrangement is such thatin timed cooperation with the other partsof the machine, the toggle is straightened andthe eccentric turns in the direction to cause the counter molding pressure to be exerted upon the counter supported between the molds.

Incidentally, it 18 to be pointed out that the center mold carrier is provided with two spring-pressed, side mold engaging, thrust slides 80 provided with rolls upon their ends which engage the surfaces on the side molds and which contribute to cause the molding pressure to be exerted upon the side molds when the cenierinold is raised. p The Wiper 12 carries a wiper blade which is secured to the wiper by screws. To the wiper-is connected the link 91 which is ,pivotally connected to the arm 92 provided nvith a hub 93 mounted on the shaft wtsupported. iirbi-ackets 95 secured on the top of the frame of the machine. The hub 93 iS'alSo proy ided with the arm, 96, to the rear end of which is pivotally connected the link 97 which. at its lower end, is pi votally connected at 98 to theuu'm 100 pivotall y mountedat IUl-oii a stationary pint of the machine. The huh 102 of the arm 100 also carries two cum armone of them the cam arm' 103 which carries at its "end the cam roll 104 which engagcs'th'e cam disk 105 mounted on the cam shaft 106 supported in lxaarings in the frame of the machine; the other cam arm, 107, mounmd on the hub 102, carries at its end the cam'ifoli 168 which engages the cam disk 110 mounted on the same cam shaft 106. i

The above-descri hed arrangement. the contour of the cams. and the timing of the parts,

are such that after the molds arev closed upon.

the counter, the wiper is actuated to move downwardly over the front faces ofthe molds and thereby flange the edge of the counter over the front surface of the center mold. after which it is again lifted and the molds are opened. l

The feeder consists of a device into which the counter is introduced by the operative, which holds the (munter and carries it to position between the compressing moldsl In general, the feeder consists of a plate having; counter-holding" devices in it, which is car-- ried by an arm pivotall supported in position to swing;' so as to move from a position of clearance toe position of presentation of the counter to the molds. Specifically con- I sidered. the feeder is mounted upon an arm 12.0 which is secured to the rock shaft 121.

pivotally mountcd in the bracket on the center mold carrier Also mounted on the shaft 121 is the arm 11-3 to the end of which is secured oneend of the link indicated in a general way by the reference ciutracter. M4, the other end of which is secured to the upper end of the feeder operating: arm. 125. The arm 125 is mounted on the'hub 126 sup ported on the shaft 127 carried by the braclo ets 128. Upon the hub 126 is also secured the feeder cam arm v130 which "cai-ries'upon its lower end the cam roll 131 which takes against the cam formed. by the cam part 132 secured on one side of the gear-133 by mca'ns of the cap bolt 13% which passes through a slot in the cam part 132 so as to afford provision for varying the timing. of the opera{ tion of the feeder. The other cam part 135.

is similarly secured in an adjustable manner to the said 133, and, togetl'ier, they form a partially closed campath for controlling the n'rovements of the cam arm 130. The

" gear 133 rotates in the direction of the arrow 136 and it will be observed that the shapes of the cum parts are such that the feeder is lifted and. then held in a stationaiy position for a spell while the molds are closing upon the counter, and that thereafter the downward movement of the feeder begun by the engagement of the cum part with the cam roll 131, after which the feeder is reis provided with two out-turned ears 14.4 which are received in top andbottom recesses 145 and 146 in the rear end of the outside grips'lll. T he screw 14:3 forms epivot by which the grips are hinged together. On the rear end olljthe outside gripsll are secured the angle pieces 1 17 which extend downward from the outside grips 141 and forwardly under the plate 140. Upon the forward ends of these anglepieces 147 are formed the springseats 14:8 and between these two-spring seats the spring 150 is placed which exerts an outwei'd pressure tending to hold the parts apart-and 1 y t the'stop screws 151 "edjustehly mounted iu the downwardly extended webs 152 of. the plate 140; In order to adjust the positionof the grips at their rear ends so that they shall; hold the counter n wrrect position to enter the space between themolds, the screws 151 i are. adjusted inwaid, or outward, as the cow may be, the springiorcing thein outwexd to follow-the'screwfs Whenthey are Withdrawn,- Set nuts are employed to fasten the ailing ing screws 151 in. adjusted position. who

It will thus be seen that by turning all of them in the some dire-$1011 the feed plate can be raisedor lowered end the screw 180 will securethe feed plate in the adjusted position; also thet when it is desired to change the inclination of the plate this can be accomplished by tuming some of the screws so as to move the plate in the desired direction The feed plate support 182 is sdjusteloly secured to a,

lateral projection from the feed slide 184 by means of the cap'vholt 185 which passes through it slot 186 inthe bracket of the feed slide and screws into the feed platev support The slot 186 provides for lateral edjustment, of the feeder so that it my head justcd to present the ooiulter correctly let ,erally with relation to the mold. Projecting Eromthe iuiderside of the-feed plate 182 are the ends of two pins 181' which engage a groove 188 in the upper sideo'i the lateral bracket on the feed slide 18%. These pins prevent the feed plate from any turning movemetn of the feed-plate support on the bracket of the feed slide. -The feed slide 184 is provided on its underside with 'u dovetail groove which receives a dovetail guide 189 and in order to seems a nice fit between the slide and guide an adjustable gib 190 is provided, screws 191 afiording means foradjustment of the gib. The slide 184; is yieldjngly pressed outwardly "by means of the spring 192 which is wound on the spring suppoitwii in turnadjustably scoured by the bolt-194; to the side, of-the am 120. I By loosening the bolt 194 and turning the spring support'193 the tension of the spring-may be 'edjufied, Theoutward movement of the slide 184 is limitedhy the engagement of the stop pin 1%, (see Fig; 8) secured in them!- derside-of the slide 184, with the stop 196 adjustebly secured by means of the cap bolt wardly from it and engage the under sur- 197 to the arm 120. The spring normally holds the slide 18 1 against thisv stop at all times except when during the operation of the machine the feeder has presented the counter to the mold and until the upward movement of the feeder due to the upw'erd' move- ,ment of the center mold cm'rier has risen so cause the feedslide184 to strike the stop 200 adjustably secured to a sta- 'tionerypert of the machine. v (See Figs. 1

and 2.) During the latter part of the upward movement'ot the center mold carrier, which movement, of course, is participated iii-by the feeder which is cerreid thereby, the counter is arrested by'its' engagement with ,the side molds, and during the nip of the molds the center mold carrier rises'and unlexthe feed sli'cle' were arrested in its rising messes movement by engagement with the stop 209,

The rock. shaft 121' is provided with' an arm 210 having a set screw 211 in its end which, when the feeder is actuated to present a counter to the molds, engages the surface of the bracket 122 so as to stop the feeder in correct position with relation to the mold. (See'Figs. 1 and 2.) Furthermore, it is to be. noted inconnection with the link 124 bymeans of which the motion (see Fig. 2), that [it has provision for I lengthening. andslurrtening it consisting of the right and left screwthreaded bolt 21.5

secured at one end by a set nut. Further: more, one end of this bolt screwed into a block. 216 which is receivedin a hole .21."? in the member 218. This block 21s is supported by a spring in the bottom of the hole and normally held from movement outward by a springlatch 219. If a counter should become crumpled during the act of presenting it to the molds and thereby obstruct the feeding movement of the feeder, the spring under the block 216 would yield therebypermitting the arrest of the movement of the feeder without breaking of any parts.

Whenthe feeder falls it strikes an adjust able stop 220 (see Fig. 10) surfaced with leather 221 and supported by an adjustable screw 222, which screw is supported in-the. bracket 223 pro ecting forward from the center mold carrier.

For the convenience of the operator in presenting the counter lo the feeder, afeed table 230 is provided supported in adjustable position from the li raclcct 223. feed table 230 may be adjusted so as to bring its upper surface into the plane ofthe upper.

surface of the feed plate HO. so the opera tive may bend a counter into U-shaped form and press it down upon thc'feedtable and then, when the feeder falls into open position, 'all theoperative required to do is to slide the counter forward, cnteringiits edges between the counter grips 14 and 1 22. This contributes to the case of fcedingthc machine.

In doffing the counter the center mold is tipped'outward from between the two This molds, so that the counter. may be lifted off. In describing the center mold, reference was made to the pivotal support thereof upon its base. The means for tipping the center mold consists of the link 240 which is pivotally connected at its forward end at 2&1 to the center mold. its end being, re-

ceived in a recess 242 in the back of the center mold. The rear end of the link 240 is pivotally attached at 243 to one arm 244 of a hell crank lever pivoted on the shaft 245 supported in hearings. 246 secured to the frame of the'machine. The other arm 247 of the bell crank lever is connected by means of the link 248 to the cam lever 250 pivoted at 251 to a bearing 252 secured to the frame of the machine. This cam lever 250 carries,

the cam roll'253 on the end of a stud secured to the lever, which projects through the slot 254:, in the frame of the machine and enters a cam groove 255 in the cam 256 secured to =to its original position. By reference to Fig.

4. it will he observed that after the mold is tipped outward, it is held stationary in outward position a shorttime while the dotting operation is performed. The dofier properly consists of a device provided with a. finger which slides under the flange at the rear of the heel of the counter and lifts the counter olf of the center mold. The doifer 1s a vices for engaging counters, which operate one after the other for the purpose of doffing the counters from the center mold. Each of the two doffer arms 26.0 carries at its end a dollar. finger 261 which is a flat piece of metal-secured to the side of the dofler arm 260. The advancing edge of the finger 261 is beveled so that. it may slide under the dmvnturned. flange of the counter between the flange and the front surface of the center mold. Then it rises and engages the inside of the rear-of the counter-near the flange thereof, and by its continued'movement it lifts the counter oil of the center mold. The doifer arms v260 are each pivoted at their inner ends upon pins .262 to the doiicr carrier 263, which carrier is provided with a hub 264 secured by a double affair, having two of these de-,

drive' pin 265 to the (letter shaft 266. The I dofief carrier 263 is a slotted piece, and the This cover it plate is secured in place by u A. cover plate 270 covers the open end of the dolfer carrier and closes the slots 267.

'Thc opemng movement of the toggle is accompanied by esort of pound at the. ex treme end ofthe movement, and n order to .avoidt-his a friction drag or shock ehsorhing device is connected to the center mold carrier lever. A friction device carried by the holder 310 is attached to the ratchet 3H and an arm 312 loosely pivoted on the shaft carrieso pawl 313 which engages the teeth, of this ratchet 311. The pawl is springpressed, as shown. The free end of the pawl. arm 3121is connected bvmeenscftlie v limit 314 with the. center mold carrier lever a 45. Upon, the straightening on closing movement of the toggle, the pawl goes beck' The devices for heating the molds consist of'electrical heating units32fi, 3213116.

'he-sion of the counter to the molds.

hi is especially important in .connection wit h fiber counters, as it prodoees eYoo mter which retains its shape after. Being incorporated in a shoe in spitev of themoisture due toperspiretion or expcsure jv'eter. 1 It use o'l this niatcrial, altho seems, and the fact is believed to be, that.

the counter is removed from the molds 'it springs away from the form which it wascaused to assume under pressure, whereas,

in molding with hot molds, according to the present invention, the counter when removed from the molds springs back very much less, so that counters of uniform shape are produced. lhe counters molded by the use of cold molds springback when removed from the molds to 'difierent degrees,'dependingsomewhat upon the condition of the counter when itwas inserted in the mold, so that the product is non-uniform'in character, whereas, in molding -counters according to the present invention, the counters respond very closely to the form" of the" molds and spring back a substantially uniform amount, a result of which it is possible to obtain, counters which very closely approximate the shape of the last upon which the shoe is to he made in whici the counters are used. The counter blanks are preferably superficially coated or saturated with parallin, but the water-resistingcharacter ol? the product is observed .without the its use enhances that quality.
